Kids' Science Challenge #10 Stumper Question: Some types of higher animals such as reptiles and amphibians are described as being cold-blooded. Does this mean that their body temperature is always cold? Answer: NO. Animals described as being cold blooded do not have the built-in, internal ability to regulate their body temperatures and so their temperatures vary as the temperature of their surroundings varies. When the surroundings are cold the animals will be cold. Movement and some other physiological activities will create some body heat so when the air is freezing the animal will not necessarily be frozen but they will be sluggish or hibernating. When the surroundings are hot a cold blooded animal will often have to stay in shade or under cover in order not to become seriously overheated.
